T0 to whom it may concern:

Be it known that we, AUGUST ZILLER and HENRY BOUOHARD, citizens of theUnited States, residing-at Austin, in the county of Travis and State ofTexas, have invented certain new and useful Improvements in Hay-Presses, of which the following is a specification.

This invention has relation to presses having a rebounding andintermittently-operated plunger, and aims to provide a novel andfication, still the preferred embodiment of the invention is illustratedin the accompanying drawings, in which 7 Figure 1 is a perspective viewof a press embodying the invention. Fig. 2 is a side view, a portion ofthe baling-chamber and the hopper being in section. Fig. 3 is a sectionon the line X X of Fig. 2, showing the parts on a larger scale and thesweep disconnected from' the driver. Fig. 4 is a perspective view of theslide-frame, driver, and mountings therefor. Fig. 5 is a detail viewshowing a modification. Fig. 6 is a transverse section of thebaling-chamber about on the line Y Y of Fig. 2.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The component parts of the press are preferably mounted upon oppositeends of a bed or base 1, consisting of a board or plate and comprising abaling-chamber and operating means for the plunger. The baling-chamberis indicated at 2 and may be of anyconstruction and consists ofinclosing'walls and a series of strengthening and bracing frames, thelatter comprising lower transverse sills,upper cross-bars, and uprightsconnecting the sills and cross-bars and bracing the side walls of thechamber. The hopper 3 is located at the innerupper end of thebaling-chamber and receives and directs the charges to the balingchamberin the operation of the press. The upper side or wall 4 of thebaling-chamber is pivoted at its inner end and is adjustable at itsouter end by means of a set-screw 5, threaded into the cross-bar of therear bracingframe. A retainer is located immediately in the rear of thehopper and is pivoted or hinged to the crossbar of the intermediatebracingframe and consists of a plate 6 and a down- Wardly-extended lip7, beveled upon the side adjacent to the hopper, so as to admit of thecharge passing readily by the lip in the operation of the press. A cleat8 is applied to the upper side of theplate 6, adjacent to its freeend,and projects beyond the sides of the baling-chamber and is connectedat its ends to the latter by springs 9, which are of a strength to forcethe lip 7 in the rear of the charge after the same has cleared the lipin the forward movement of the plunger. Other retainers 10 are appliedto the sides of the baling-chamber and consist of flat springs securedat one end to the side walls of the baling-chamber and having theopposite end flexed so as to extend into the baling-chamher and acrossthe path of the charge, so as .to cooperate with theupper retainer orlip 7 and prevent the charge from following the plunger upon its returnstroke.

The plunger or follower 11 is adapted to reciprocate below the hopper 3,and its stem 12 is provided at its outer end with a rectangularslide-frame .13, held in place and directed in its movements by fourposts 14, projected upwardly from the bed or plate 1, said posts havingnotches 15 in their outer sides to receive the longitudinal bars of theslide-frame 13, so as to retain the same in position against casualdisplacement. A plate, strip, or board 16 extends crosswiseof the bed 1and slide-frame 13 and is secured to the upper ends of the posts 14: andis provided at its ends with cams 17, facing in opposite directions andadapted to unship the sweep 18 from the driver 19 at proper anddeterminate points in the revolution of said sweep.

The operating means comprise a shaft 20, driver 19, sweep 18, clutchbetween said sweep and driver, and a flexible connection 21, the latterbeing attached at one end to the driver 19 and at its opposite end tothe outer crossbar of the slide-frame 13. The sweep is provided with atube 22, pendent therefrom and journaled in the plate or part 16 andprovided at its lower end with a half-clutch 23. The tubular bearing 22is secured to the sweep in any substantial way and is provided at itsupper end with an outer flange apertured to receive the fasteningsemployed for attachment thereof to the sweep. The shaft is journaled atits lower end in the bed 1 and its upper end in the tubular bearing 22and is secured to the driver 19 so as to rotate therewith. A plate 24 issecured in any substantial manner to the lower end of the shaft 20 andunderlaps the bed 1 and serves to prevent vertical displacement of saidshaft,while at the same time admitting of free rotation thereof. Thedriver 19 is preferably of wood, although this is not essential, and itsperipheral portion is grooved to insure seating of the flexibleconnection 21 to efiect rectilinear movement of the plunger 11. A tubeis secured to the driver, and its upper end is provided withahalf-clutch 26 for cooperation with the half-clutch 23 in the mannerpresently to be explained. The lower end of the tube 25 is flanged tospace the driver upon the bed and alsoto receive the fastening meansconnecting the-tube 25 with the driver 19. The sweep 18 may be operatedby hand, horse, or other power and is mounted upon the shaft 20 andwithin the plate 16,- so as to receive a combined rotary and np-anddownmovement, the latter being essential to admit of unshipping of the sweepfrom the driver inorder to permit a rebound of the plunger aftercompressing the charge and to .admit of a new charge being supplied tothe baling-chamber. The rebound of the plunger is eifected by means of aspring 27, which is connected at one end to the stem 12 and at itsopposite end to the plate 16. The spring 27, which is of the coil type,is expanded as the plunger is driven forward, and the instant the driveris released from the impelling means the spring contracts and returnsthe plunger to a normal position. The sweep is forced downward to holdthe half-clutches 23 and 26 in engagement by means of a springinterposed between it and the shaft 20. In the preferable constructionthe spring is of bow form, as shown at 28, and is secured at a centralpoint to the shaft 20 by means .of a headed fastening 29, the endportions of the spring exerting a downward pressure upon the sweep atopposite sides of the shaft, whereby the sweep is held level and inclutched engagement with the driver in the manner stated. In theconstruction shown in Fig. 5

the spring 30 is of the coil type and surrounds the upper portion of theshaft 20 and is confined between a washer and the sweep.

In the operation of the press the sweep 18 is rotated and eifects acorresponding rotation of the driver 19 through the instrumentality ofthe interposed clutch, and as a result of this operation the flexibleconnection 21 is wound upon the driver and the slideframe 13 is movedinward and forces the plunger into the baling-chamber, whereby acompression of the charge supplied to said baling-chamber through thehopper is effected. When the sweep alines with the plate 16, it receivesan upward movement by riding upon the cams 17, thereby unshipping thehalf-clutches and disconnecting the sweep from the driver, whereupon thespring 27 returns the plunger to a normal position in the manner stated.As soon as the sweep clears the cams in its further movement it is moveddownward by either the spring 28 or spring 30 or like means, therebypermitting the sweep to again become clutched to the driver, when theoperation just described will be repeated. In the construction shown thesweep is disconnected from the driver twice during each completerevolution. The cams and parts of the sweep coming in contact with saidcams are protected, so as to resist wear, or, as shown in Fig. 5, aroller 31 may be applied to the under side of the sweep to come incontact with and ride upon the cams,there by reducing the friction andresistance to a minimum amount.

Having thus described the invention, what is claimed as new is 1. In apress, and in combination with the baling chamber, and plunger,operating means for said plunger comprising a shaft journaled at itslower end, a driver journaled to said shaft, a cam-plate, a sweepjournaled in said cam-plate and forming a bearing for the upper end ofthe aforementioned shaft, a clutch between the sweep and driver, andconnecting means between the plunger and driver, substantially as setforth.

2. In a press, and in combination with the baling-chamber and plunger, ashaft, a driver journaled to the shaft, a cam-plate,- a sweep journaledto the cam-plate and forming a bearing for an endportion of theaforementioned shaft, a clutch between the driver and sweep, and aspring confined between the projecting end of the shaft and sweep tonormally hold the parts of the aforesaid clutch in engagement,substantially as described.

3. In a press, and in combination with the baling-chamber and plunger, aslide-frame connected to the stem .of the plunger, posts notched intheir outer sides to receive the 1ongitudinal bars of the slide-frame tohold the latter in place and direct it in its reciprocating movements, acam-plate secured to said posts, a sweep journaled to the cam-plate, ashaft journaled at one end to the sweep and at its opposite end to thebed of the press, a driver journaled to the shaft, a clutch having itscomponent parts applied, respectively, to the driver and sweep, a springfor effect ing a rebound of the plunger, and a. flexible connectionbetween said plunger and driver, substantially as specified.

In testimony whereof we aflix our signatures in presence of twowitnesses.
